That is my point. It is possible to pass multiple arrays, using array reference

Well, you missed the point of Re: How to declare arrays and scalars together? which is, you're only passing lists, you cannot pass an array, an array and an arrayref aren't identical, you need to de-reference an arrayref, but not an array

Given my @one = (1,1); my @two = (2,2);

This  foo( @one, @two ); is basically the same as  foo( 1,1,2,2 );

With the appropriate prototype  foo( @one, @two ); could also be basically the same as  foo( \@one, \@two );

If you use  foo( \@one, \@two ); then in sub foo you would need to write     my( $oneref, $tworef ) = @_; which is not the same as  my( @one, @two ) = @_;

You're always passing lists to subroutines
